Make sure you have the power cord plugged in - if it’s just connected by USB, it will talk to you but there will be no power to the motors. I know this seems like a dumb and obvious thing to start with, but make sure both USB and power is applied.

Alarm 9 and 8 are usually caused by users forgetting to turn power supply on.

Do the motors try to move the laser???

IF motors DO move …ALARM:9 means that either the machine is moving in the wrong direction trying to find the switches, or they didn’t trigger, and both point to a wiring issue or a settings issue. The machine comes pre-configured, so unless you altered settings it’s likely wiring. Double check the wiring to the limit switches, and make sure the wires to the switches are coming out of the proper side, and the switches are mounted so the machine is making contact with them correctly.

Have you added anything to the laser? ie: Z-axis adjuster?

Let us know if you get it figured out.

@kerrylaw I looked over the laser again. And here’s what I did.

I looked at the assembly instructions and found out that I installed the limit switch the wrong way. I went away and corrected it.
I have both the power cord and usb connected.
As for the wiring I double checked the control panel as well as the x-axis and y-axis motors and they both work fine, however I’m still getting this error.
